I'd like to be able to break lines longer than 100 characters into multiple lines of less than 100 characters in IntelliJ IdeaVim. The Vim solution in vim command to restructure/force text to 80 columns doesn't work.
It's not implemented in IdeaVim yet. Feel free to vote for https://youtrack.jetbrains.com/issue/VIM-1310 about :set textwidth
and https://youtrack.jetbrains.com/issue/VIM-186 about gq
to re-wrap comments.
